Abstract
The utility model provides a lead wire clamping device in a sleeve lifting seat of a high-voltage transformer, which comprises a fixed base board fixed in the sleeve lifting seat, first insulation boards, second insulation boards, supports and lead wire clamping supports, wherein the first insulation boards and the second insulation boards are fixed on the fixed base board and used for embedding the fixed base board into insulation protection, the supports stretch over the adjacent first insulation boards, and the lead wire clamping supports are fixed between adjacent supports. An electric safety distance between the lead wires and the sleeve lifting seat is guaranteed on the basis that the size of the sleeve lifting seat is reduced.
Description
Technical field
The utility model belongs to a kind of high-tension transformer and makes the field, the lead-in wire clamping device in particularly a kind of high voltage transformer bushings rising seat.
Background technology
Coil head end outlet in the electric power oil-immersed type transformer all needs to cause sleeve pipe through lead-in wire through sleeve pipe rising seat mostly; In the lead-in wire spill process; Standing be equipped with support lead-in wire is carried out effective clamping, raise and reliable electrical safety is arranged apart from (referring to Fig. 1, Fig. 2) between the seat wall to guarantee lead-in wire and sleeve pipe.Rising along with electric pressure; Lead-in wire and the electrical safety spacing that raises between the seat wall also strengthen thereupon; And the creepage distance that is produced on the support of clamping lead-in wire needs increasing too, thereby the also constantly increase of the inner space of sleeve pipe rising seat, but receives the restriction of spatial synthesis layout sometimes; And from the consideration of economy equal angles, the inner space of high voltage bushing rising seat can not be amplified simply.Thereby need a kind of creepage distance that can reliably guarantee the needed electrical safety spacing of high voltage outlet and necessity, can make the as far as possible little lead-in wire clamp structure of diameter of sleeve pipe rising seat again.
The utility model content
The utility model provides the lead-in wire clamping device in a kind of high voltage transformer bushings rising seat, in the electrical safety distance of having guaranteed on the basis that reduces sleeve pipe rising seat diameter dimension between lead-in wire and sleeve pipe rising seat.
The technical scheme that the utility model adopted is: the lead-in wire clamping device in a kind of high voltage transformer bushings rising seat; Comprise be fixed on sleeve pipe raise the seat inwall fixed base plate, be fixed on the fixed base plate and fixed base plate imbedded first insulation board and second insulation board of insulation protection, use support across the support on adjacent first insulation board, the clamping lead-in wire that is fixed between the adjacent stent.
Said first insulation board is L shaped structure; Comprise and the raise support portion of parallel vertical installation portion of seat and the level vertical of sleeve pipe with vertical installation portion; Said fixed base plate is provided with mounting groove; The installation portion of said first insulation board is fixedly mounted in this mounting groove, and the support portion of said first insulation board is fixedly connected with support;
Said second insulation board is fixed on the outside of fixed base plate and parallel with the raise inwall of seat of sleeve pipe;
Said first insulation board is four, is uniformly distributed in the inwall of sleeve pipe rising seat;
Said support and clamping lead-in wire are put up " worker " font structure with propping up, and the place, four angles of being somebody's turn to do " worker " font structure is fixed on respectively on four first insulation boards.
Lead-in wire clamping device in the utility model high voltage transformer bushings rising seat has the following advantages at least: 1) fixed base plate is imbedded in the protection of insulation board; Creepage distance between lead-in wire and fixed head has also had bigger increase; Thereby under the situation that same high-tension lead-in wire passes through, can be implemented in and suitably reduce sleeve pipe and raise the seat diameter and the electrical safety distance between seat of guaranteeing to go between and raise; 2) reasonable Arrangement support has increased the creepage distance between lead-in wire and support plate; 3) suitably choose the raise diameter of seat of sleeve pipe, effectively practice thrift cost.

Embodiment
Below in conjunction with accompanying drawing the utility model device is done and to be further described:
The utility model high voltage transformer bushings raise a lead-in wire clamping device in the seat comprise be fixed on sleeve pipe raise fixed base plate 2 on the seat 1, be fixed on first insulation board 3 and second insulation board 7 on the fixed base plate 2; Across the support 4 on adjacent first insulation board 3, be fixed on clamping lead-in wire between the adjacent stent 4 with support 5, said high-voltage connection 6 is held and goes between with support 5 fixed clamp.
Said fixed base plate 2 is fixed on the inwall of sleeve pipe rising seat 1; Said first insulation board 3 is L shaped structure; Comprise and the raise support portion of parallel vertical installation portion of seat 1 and the level vertical of sleeve pipe with vertical installation portion; Said fixed base plate 2 is provided with mounting groove, and the installation portion of said first insulation board 3 is fixedly mounted in this mounting groove, and the support portion of said first insulation board 3 is in order to be fixedly connected with support 4; Said second insulation board 7 is fixed on the outside of fixed base plate 2 and parallel with the raise inwall of seat 1 of sleeve pipe; Said clamping lead-in wire is fixed therein on the support 4 through securing member with an end of support 5, and the other end is fixed on another support 4 that is adjacent, and said high-voltage connection is held lead-in wire through securing member and grips with support 5.
Said first insulation board 3 is four, is uniformly distributed in the inwall of sleeve pipe rising seat 1, and said support 4 goes between with 5 one-tenth on support " worker " font structure with clamping, and the place, four angles of being somebody's turn to do " worker " font structure is fixed on respectively on four first insulation boards 3.
Install and when using, at first confirm the diameter that the sleeve pipe that is fit to raises earlier based on the electric pressure of pass through high-voltage connection, and definite and corresponding lead-in wire size of this diameter and insulation thickness thereof; Then at 4 fixed base plates 2 of inwall welding of this sleeve pipe rising seat 1, through the reasonable setting of first and second insulation boards 3,7 and support 4,5, lead-in wire is reliably gripped, and has suitably increased the creep age distance between lead-in wire and base plate.
The above is merely a kind of execution mode of the utility model; It or not whole or unique execution mode; The conversion of any equivalence that those of ordinary skills take the utility model technical scheme through reading the utility model specification, the claim that is the utility model contains.
